I don't live near one, but one was proposed nearby, and one of the things raised that residents of the area worried about was the flashing of sunlight as the blades caused a shadow, so that would be a concern for me.

There is a mahusive one in Reading that powers an industrial estate that one of my clients is based in. It doesn't make noise, but as Bid said the blades do cause a funny flashing in sun which I find a pain.

Interesting thread. I saw a program about two years ago with people who live close to one complaining of a "whooping" type noise that stopped them sleeping. Good to hear that other people who do live near one saying that there is no noise.
